It is society's view on us on why we dont want to "improve" ourselves. When you go around telling people that your daughter's life has improved because of the CI, that she is able to hear and etc, hearing people who arent educated will take it at face value and question the Deaf community's preference to stay the way they are. Then, the Deaf community gets pissed off and say stuff like that.
I should know because I have been put in that situation too numerous times to count and it gets depressing at times.
